Translarna is currently indicated for ambulatory Duchenne patients who are over two years of age; the requested extension would have allowed for the inclusion of non-ambulatory patients in the label. PTC plans to request a re-examination of the procedure within the next two weeks and expects the new examination to last approximately 4 months.
"While we are disappointed with the current outcome of the label expansion procedure and its impact on non-ambulatory patients with nonsense mutation Duchenne Muscular Dystrophy, we are pleased that patients on Translarna can remain on treatment after loss of ambulation," said
The clinical data supporting the extension is based on results supporting the positive impact in the Force Vital Capacity (FVC) parameters for patients treated with Translarna in study 019, a long-term, open-label study, and study 025 (STRIDE Registry) when compared to matched natural history controls. This is in addition to currently approved labeling stating that the pharmacokinetics (PK) and safety profiles are comparable between ambulatory and non-ambulatory nmDMD patients, and that no dose adjustment is necessary when patients become non-ambulatory. The CHMP opined that the comparable PK may not ensure efficacy in non-ambulatory patients since muscle mass is reduced in this patient group. PTC and members of the scientific community expressed disagreement with this understanding during the oral explanation.

About Duchenne Muscular Dystrophy
Primarily affecting males, Duchenne muscular dystrophy (Duchenne) is a rare and fatal genetic disorder that results in progressive muscle weakness from early childhood and leads to premature death in the mid-twenties due to heart and respiratory failure. It is a progressive muscle disorder caused by the lack of functional dystrophin protein. Dystrophin is critical to the structural stability of skeletal, diaphragm, and heart muscles. Patients with Duchenne can lose the ability to walk as early as age ten, followed by loss of the use of their arms. Duchenne patients subsequently experience life-threatening lung complications, requiring the need for ventilation support, and heart complications in their late teens and twenties. More information regarding Duchenne is available through the
